Resonance 6 A closed column pipe has an antinode at both ends.
{"Image DocumentName": "Harmonics of Closed Pipes", "Image ImageDescription": "A closed pipe is slightly different. Because there is a node at one end and an antinode at the other, the pattern is different. 1. \u03bb The fundamental frequency is only a quarter of a wavelength. The next harmonic occurs at three quarters of a wavelength. This is the third harmonic \u2013 the even number harmonics do not exist for closed pipes.
